Featured More gem ID please

Ive been playing with my new gem tester (aka Mary Contrary) to decide if it's working correctly. Decided I wouldn't know unless I had verified samples to check against. My problem is that despite googling I'm confused as to which gems go under a different name. i.e is Beryl a type of quartz, is jasper hessonite etc?
I know it has its limitations and can just give me a guideline. I'd just love some help to interpret my results with the verified gems please.
Thankyou


Accurate results- Hessonite,Peridot,Amethyst,Aquamarine,Jadeite,Quartz,sapphire, Ruby,diamond.

Unsure-
Beryl- tested as jadeite/quartz
Jasper- hessonite/jadeite/quartz
Carnelian-jadeite,nephrite/spessartite
Sodalite-Aquamarine/Jadeite/Nephrite/paraiba
Chrysoprase-Aventurine/Demantoid/peridot
Garnet-Amethyst/Aventurine
Lapis L-Aquamarine,Iolite,Nephrite
Serpentine-Aventurine,Demantoid,Jadeite,peridot
.

 

Beryl is much higher on the Mohs scale than quartz. Beryl is precious, quartz is semi-precious. For beryl think emerald, aquamarine.

Hessonite is an orange-brown garnet, much higher on the Mohs scale than jasper.

 

I don't know if these testers are based on testing hardness (Mohs scale) or rather warmth conductivity.
You still can diffferency jasper, opaque, from transparent or totally different looking stones
@Any Jewelry, to be totally accurate

, and before HollyBlue points it, there is only 4 precious stones in definition:
Diamond, Ruby, Sapphire and Emerald
Others are semi precious, and lower are the ornamentals ones

True. I will remove the 'offending' part to avoid confusion.

 

This.
At least it seems accurate with the precious gems,just goes off piste a bit with the less exciting ones!.

 

Some members of the quartz family often seen in jewellery:

• rock crystal
• amethyst
• citrine
• smoky quartz
• rose quartz
• aventurine
• tiger's eye
• the chalcedonies: carnelian/cornelian; sard; sardonyx; black onyx; chrysoprase; heliotrope (bloodstone); agates; jaspers

 

You are saying Hessonite is accurate but unsure about garnet? Hessonite is garnet.

 

So when I test confirmed Hessonite it says it's Hessonite which is fine but when I test the confirmed garnet it says it's amethyst or Aventurine although it was an unpolished piece which I suppose could throw it off? Some other garnet pieces it says are almandine which I know is garnet.

 

Gem testers only give an approximate type,garnets are a family group and contain different minerals.You may need to look up info for your tester and see what it says about specific gems when testing them...... https://geology.com/minerals/garnet.shtml

 

K, do you have any gemstone books? There are some with very thorough information on the physical properties of stones, which stones look similar to the one you are researching (so could be an option too), etc.
I don't know of any English language ones, but I am sure the others can advise you.

 

Are you watching my house? Spooky!
This just dropped through the postbox!
On first glance there aren’t many photos though ( see the level of amateur you are working with here?)

 

Gem id book with hasn't MANY PHOTOS?
For blind people?
At least, Internet and Google images are our friends

 

It's an interesting concept isn't it?. I misunderstood what I was buying. I thought it was going to have pretty pictures of all the different gems but it's more scientific stuff.........
Here's a small snippet for light reading, all good info but I think I may search out a Dorling Kindersley children's version

 

I'm now intrigued as to why Andradite is described as 'very lively'!....?

 

This I feel maybe more my level.

Sorry, no idea why this photo is so huge!
